2013 is coming to an end, which means it’s time to reminisce on the headline-making moments that took place over the last 12 months. Yes — a whole lot more has gone on in the celeb-verse besides Miley Cyrus’ 2013 VMAs performance (which, 3 months later, people are still talking about).

While some celeb couples, like Khloe Kardashian and Lamar Odom, are seemingly still trying to work on their troubled relationships, many big-name duos decided to call it quits for good this year. Check out our round-up of the 10 biggest celeb breakups of 2013:

Their romance was short-lived, but at the beginning of 2013, it was certainly all anybody could talk about. Taylor and Harry made a pop power couple when they began dating in October 2012 and became immediately smitten with one another (although, with Taylor in the picture, it was probably more one-sided). But, at the beginning of January, the couple reportedly had a blow-out fight while on vacation, causing the “Red” singer to jet home early…and leave her playboy ex to continue the party in the British Virgin Islands.

Stacy was relatively unknown before she became George’s arm candy in 2011. Although they dated for two years, their demise wasn’t all that shocking, considering the A-lister has openly said in the past that he doesn’t plan to marry again. However, after the split in July 2013, Stacy told reporters that she planned on staying friends with her ex, and added that “nothing really dramatic happened.”

Now, she’s dating entrepreneur Jared Pobre, while George has been linked to numerous women, including his Gravity costar Sandra Bullock, since the breakup.

Despite their 35 year age difference, Clint and Dina were married for 17 years. In August 2013, though, the 48-year-old admitted that they had been living separately, and she filed for divorce from her 83-year-old husband in October. The couple share a daughter, Morgan, who Dina asked for full custody of in her divorce filing.

Julianne met Ryan when she was 22-years-old and fairly new to the entertainment industry. Although he was 13 years her senior, the couple stayed together for nearly three years. Eventually, their split was announced in March 2013, with busy schedules and long distance as the reported cause.

In September 2011, Ian confirmed that he was dating his Vampire Diaries costar, although the duo had been linked as an off-screen couple for many, many months before then. In May 2013, they confirmed their split after nearly three years together. After the breakup, Nina was linked to Julianne’s brother, Derek Hough, but their relationship was short-lived…and she’s even been reportedly hooking up with Ian again!

If you’ve seen photos of these two recently…you might not even know they weren’t still together! But, alas, Miranda and Orlando announced their separation in October, admitting that they had actually ended things a few months prior. Neither the actor or model, who were married for more than three years, have filed divorce papers yet, and they’ve since been spotted together, with their son, Flynn, on more than one occasion.

Nearly a year after Star first reported the marriage trouble between the reality star couple, Kris and Bruce finally decided to announce their separation. In October 2013, they admitted that they’d been living apart, and had actually separated a year earlier. Regardless, the exes, who were married for 22 years, remain close and still consider each other family, explaining that their relationship is better off while their living separately. No divorce papers have been filed, and Bruce will continue to appear on Keeping Up With the Kardashians.

Speculation that things were going south for this young couple began well before their reps confirmed the breakup in September 2013. Although Miley vehemently tried to deny any relationship issues by pointing out that she was still wearing her engagement ring throughout the spring and summer, her public image eventually got to the Australian actor. An exact reason for the split hasn’t been given, although it’s pretty obvious that the exes were just on two completely different paths. Just days after the breakup announcement, Liam was photographed kissing Mexican actress Eiza Gonzalez.

In July, Star was first to report the news of Catherine and Michael’s separation. Weeks later, at the end of August, their rep confirmed the split. No divorce papers have been filed, but, like Kris and Bruce, the exes are living while “evaluating” and “working on” their marriage. Despite their 25-year age difference, they were married 12 and a half years before decided to cool things off

The trouble began for these Twilight costars in June 2012, when photos surfaced of Kristen (who Rob was dating at the time) kissing her married Snow White and the Huntsman director, Rupert Sanders. However, the British actor stuck by her for the next several months, but ultimately couldn’t get over her affair. Their split in May 2013 was highly publicized, although neither ever talked openly about the breakup or relationship. In fact, although they were linked since 2008, Kristen didn’t even acknowledge that they were a couple until issuing a public apology after the cheating scandal!

Luckily for Robsten fans, they seem to have gotten over any animosity that the breakup might’ve caused. Although they’re not back together as a couple, they were spotted meeting up in October.
